This the same quality Western Digital hard-drive that has 4.7ish stars with almost 2,000 reviews except with the better form factor of 2.5" so it can slide right into your SSD trays and you can do away that cluttery hard-drive bay. I believe @ $60 it is ~$10 too expensive, which is why I give it 4 stars. Other than that, quality product for that extra storage space we all end up needing for those dumb pictures, movies, and files you haven't looked at for years, but aren't getting rid of just in case :)
